There are two types of contact transmission: direct and indirect. Direct contact transmission occurs when there is physical contact between an infected person and a susceptible person. Indirect contact transmission occurs when there is no direct human-to-human contact.
What are the two 2 modes of transmission of infectious diseases?
Direct: involves direct body surface to body surface contact and physical transfer of microorganism between an infected or colonized person to another person by touch. Indirect: involves contact between a person and a contaminated object.
What are the different forms of transmission?
Modes of transmission
- Direct. Direct contact. Droplet spread.
- Indirect. Airborne. Vehicleborne. Vectorborne (mechanical or biologic)
What are the 4 routes of transmission?
The transmission of microorganisms can be divided into the following five main routes: direct contact, fomites, aerosol (airborne), oral (ingestion), and vectorborne. Some microorganisms can be transmitted by more than one route.
What are the 6 modes of transmission?
The modes (means) of transmission are: Contact (direct and/or indirect), Droplet, Airborne, Vector and Common Vehicle.

Is mode of transmission by kissing?
Kissing offers many health benefits, but may also transmit a small number of disease-causing bacteria and viruses. Bacteria and viruses in the saliva or blood of one person can be spread to another person by kissing. Some diseases are more easily spread than others.
What is the mode of transmission of Covid 19?
SARS-CoV-2, the virus that causes COVID-19, spreads from an infected person to others through respiratory droplets and aerosols when an infected person breathes, coughs, sneezes, sings, shouts, or talks.
What is the difference between transmission and infection?
The crux of the distinction is this: contagious diseases are spread by contact, while infectious diseases are spread by infectious agents.
Which of the following is the most common mode of transmission?
Contact transmission. The most common mode of transmission, contact transmission is divided into two subgroups: direct contact and indirect contact.
Which disease is spread by droplet transmission?
Measles and TB are airborne-exclusive diseases. There are several other diseases that spread through respiratory droplets, which can exist either in the air or on surfaces. These diseases include: Chickenpox.
What are standard precautions?
Standard precautions are a set of infection control practices used to prevent transmission of diseases that can be acquired by contact with blood, body fluids, non-intact skin (including rashes), and mucous membranes.
What are the 3 major portals of entry for disease?
Portals of entry into the human body include:
- Inhalation (via the respiratory tract)
- Absorption (via mucous membranes such as the eyes)
- Ingestion (via the gastrointestinal tract)
- Inoculation (as the result of an inoculation injury)
- Introduction (via the insertion of medical devices)
What are the different ways in which infectious diseases can spread?
Infectious diseases commonly spread through the direct transfer of bacteria, viruses or other germs from one person to another. This can happen when an individual with the bacterium or virus touches, kisses, or coughs or sneezes on someone who isn’t infected.
